Abstract

The invention discloses a wetting agent capable of inhibiting dust flying. The wetting agent comprises 0.05-0.25% of sodium carboxymethyl cellulose, 0.3-1.2% of polyacrylamide, 0.2-0.4% of polyoxyethylene fatty alcohol sodium sulfate, 0.1-0.5% of sodium alpha-alkenylsulfonate, 0.3-1% of corn starch grafted sodium acrylate, 0.08-0.13% of silicone resin polyether emulsion, 0.1-0.5% of dodecyldimethylbetaine, 0.1-0.3% of carboxymethyl chitosan, 0.05-0.1% of dioctyl sodium sulphosuccinate, 0.4-0.6% of ethanediol, 0.2-0.4% of calcium chloride and the balance of water. The sprayed fog drops can quickly capture and wrap the dust particles, thereby increasing the particle settling speed. The sprayed fog drops can be covered on the dust on the coal rock surface and ground surface to prevent secondary flying dust, thereby enhancing the dust removal efficiency.

Description

technical field [0001] The invention relates to a wet-type dust control wetting agent for coal mine underground working faces, in particular to a wetting agent capable of suppressing flying dust. Background technique [0002] With the improvement of coal mine mechanization in our country, in the process of coal mining and tunneling in the underground working face, a large amount of dust will be generated by the extrusion and throwing of the coal rock mass by the shearer and roadheader picks. According to actual measurements, without any dust prevention measures, the dust concentration of fully mechanized excavation face can reach 2000mg / m 3 -3000mg / m 3 , the dust concentration in the fully mechanized mining face can reach 2500mg / m 3 -3000mg / m 3 , and the fully mechanized caving face can produce a large amount of dust due to the process of moving frames and coal discharge, and the instantaneous original total dust concentration of some coal mines is even as high as 8000mg / ...
